A large supercharged, two-stroke cycle, diesel ship engine with a displacement of 196 liters operates at 220 RPM. The engine has a delivery ratio of and uses fuel oil that can be approximated as at an air–fuel ratio of The ship is equipped with an ammonia injection system to remove NOx from the exhaust.

Calculate:

(a) Amount of NO entering the exhaust system if 0.1% of the nitrogen in the air is converted to NO. (Assume no other forms of NOx are produced.) [kg/hr]

(b) Amount of ammonia to be injected to remove all NO in the exhaust by the reaction given in Eq. (29). [kg/hr]
